I use Linux, but for/in Windows, the UDF always uses the full disc drive’s speed to write the data. Even if I add a line to a text file, the disc drive first accelerates to full speed, then writes the data.

We all know the disadvantages associated with high, especially maximum burning speed.

Is there any way in Windows to decrease the disc speed for UDF (live data file system)?

It has been said that, at least for some versions of Windows, you can set the IMAPI burning speed using the settings for the burn-to-disc function in Windows Media Player (low - medium - high). I have not been able to verify this and (or this and other reasons) gave up on using this method in favor of third-party software.
